An anionic regulation mechanism for structural reconstruction of sulfide electrocatalysts under oxygen evolution conditions
An anionic regulation mechanism for structural reconstruction of sulfide electrocatalysts under oxygen evolution conditions Chang-Xin Zhao, Jia-Ning Liu, Changda Wang, Juan Wang, Li Song, Bo-Quan Li and Qiang Zhang Abstract Sulfide has long been regarded as high-performance electrocatalysts for oxygen evolution, yet the actual structure of its active sites under working oxygen evolution conditions remains controversial.
N-doped hollow Fe0.4Co0.6S2@NC nanoboxes derived from Prussian blue analogue as sodium ion anode
N-doped hollow Fe0.4Co0.6S2@NC nanoboxes derived from Prussian blue analogue as sodium ion anode Herein, a bimetallic sulfide Fe0.4Co0.6S2@NC nanobox was prepared via a simple two-step synthetic route. The N-doped carbon coated hollow nanobox was derived from Prussian blue analogue (PBA) and applied for SIB anode. As expected, it exhibits a high capacity (486.6 mAh/g at 0.1 A/g) and displays an excellent cycling stability (230 mAh/g at 10 A/g after 900 cycles).

eg occupancy as an effective descriptor for the catalytic activity of perovskite oxide-based peroxidase mimics
Abstract A peroxidase catalyzes the oxidation of a substrate with a peroxide. The search for peroxidase-like and other enzyme-like nanomaterials (called nanozymes) mainly relies on trial-and-error strategies, due to the lack of predictive descriptors. To fill this gap, here we investigate the occupancy of eg orbitals as a possible descriptor for the peroxidase-like activity of transition metal oxide (including perovskite oxide) nanozymes.
Confined Bimetallic Phosphide within P, N Co-doped Carbon Layers towards Boosted Bifunctional Oxygen Catalysis
Rational design of bifunctional oxygen electrocatalysts with high activity and low cost is crucial but still challenging for the development of rechargeable energy storage devices. In this work, a novel bimetallic phosphide confined within P, N co-doped carbon layers is achieved through a space-confinement phosphorization strategy.
